My patience comment was in reference to
@BrokenTwin's post #632 which reflects that his latest RPG provides a number of non-traditional options for one's character's heritage which means his views must have changed.
I honestly think it is about settings...if you grew up with Dragonlance not having orcs and Mystara not having giff then you're likely not going to start promoting lore that alters that original version of those settings. New settings do not have lore-luggage issues.
EDIT: And he does reference settings quite a bit in that post.
The PHB was often the manual for these a-e D&D worlds. Now you introduce 2 species alien to the lore of these worlds, you're bound to have push back. Time passed, new worlds, new lore, less pushback.
